BUTTON.

QPECIPICATION farming part of Letters Patent No. 363,285. dated May 1'7, 11887.

Application filed February 14, 1887. Serial No. 227,540. (No model.)

To aZZ whom t may concern.-

Be it known that I, J OnN CosrELLo, a citizen of the United States, and a resident of Attleborough, in the county oi Bristol and State of Massachusetts, have invented certain new and useful Improvements in Buttons; and I do hereby declare that the following is a full, clear,

and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specication, and in which Figure l is a perspectiveview, seen from the under side, ofV my improved button, showing it ready for insertion in the button-hole. Fig. 2 is a similar view of the button, showing it as it appears after being inserted and locked. Figs. 3 and 4 are sectional views taken through the shank of the button in the two positions shown in Figs. l and 2. Figs. 5 and 6 are perspective views of a modified form of the button, showing it ready for insertion and as it appears after being inserted and locked; and Figs. 7 and 8 are sectional views taken through the shank of the button .in its two positions.

Similar numerals ot' reference indicate correspondingparts in all the figures.

My invention has relation to that class of buttons having a shank provided at its lower end with a radiating arm, and having the said shank journaled to revolve within aiat shank provided with another radiating arm, so that the arms may be turned to point in the same direction, when they may beinserted through the button-hole, whereupon the head of the button and the inner shank may be turned, bringing the arms to project in opposite directions, securing the button in the hole; and it consists in the improved construction and combination ofparts of such a button, as herein-A after more fully described and claimed.

In the accompanying drawings, the numeral l indicates the head of the button, which may be of any desired shape and material, and which may be ornamentedin any desired manner, and from the back of this head projects the inner or revolving shank, 2, which is provided at its lower end with a radially-projectn ing arm, 3, projecting in a plane parallel to the plane of the back of the head, said head, shank, and arm being rigidly secured together.

The stationary arm 4 is preferably of the. same shape and size as the revolving arm, and is formed with a flat shank, 5, slitted transversely, so as to form a central bulging strip, 6, and an upper and lower strip, 7, bulging in the opposite direction, the said strips forming a bearing for the revolving shank, and the dat shank and the arm are preferably formed from one plate cut and bent into the shape of the parts.

The upper end of the dat shank is cut out to form two projecting lugs, 8, at the side edges, and these lugs engage notches in the opposite edges of l a spring-plate, l0, rigidly securing them together. This spring-plate has slightly downwardly-curved ends, and provided with upwardly-projecting lugs 11 upon one side, near the ends, which lugs may engage corresponding recesses, 12, in the under side of the bacleplate, the lugs being preferably formed by punching or depressing the metal of the Y the lugs will likewise engage the recesses or. notches, so that the arms may be locked in these two positions, the springiness of the springplate l0 allowing the lugs 11 to be released from the recesses or notches 12, and at thesame time holding them suiiiciently firmly in the same to prevent the accidental turning of the Shank.

The arms are brought to point in the same direction when the button is to be inserted into the buttonhole, when the arms and their shanks may be slipped into the hole, and when the arms and Shanks have been inserted the revolving shank and arm are turned, the flat shank being held by the edges of the buttonhole, and the arms will point in opposite directions, preventing the button from being withdrawn, the lugs upon the spring plate holding the arms in their proper positions, resting in the recesses or notches.

In the modified form shown in the last four figures of the draivings the head is provided upon its back with an annular plate or ring,

13, having two diametrically-opposite notches, 14, in its inner edge, and the dat shank is formed with two legs, 15, revolving with their ends Within the annular plate, having the outer edges engaging the notches in the edge of the said plate, the said legs and notches performing the saine duties as the spring-plate with its lugs and the recesses or notches in the backplate in the first-described button.

The bearing for the revolving shank is formed in the end of a tongue, 16, vcut out of the stationary arm, the bearing for therevolving shank and the head being formed by the annular plate and the lcgs of the stationary shank at the upper ends of the same.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- In a button, the combination of a iat shank having its middle slitted transversely to form strips bulging in opposite directions, tor-ming a bearing, and having a radially-projecting arm at its inner end, and having projecting lugs at its outer end, a head having a shank revolving within the bearing of the 'iat shank, and formed with a radially-projecting arm at :its inner end, and having diametricallyopposlte notches in its backplate, and a sprlng-plate secured With notches in its side edges to the lugs upon the end of the dat shank, and having its bulging ends formed with lugs engaging the notches in the back-plate, as and for the purpose shown and set forth.

In testimony'that I claim the foregolng` as my oWn I have hereunto affixed my signatur in presence of two witnesses.

PHILIP E. BRADY, J oHN REYNOLDS.
